Coilover damper adjusting knobs are missing?
 

how do I adjust the damper if the knob is missing? I tried to turn with a hexagon tool, but the whole cap moves. Any idea?

Both my BC racing and TEIN have the knobs missing :(

Maybe it is adjustable at the bottom of the strut/damper.....

Allen wrenches (aka hex tools) will not fit, hence why it is not working. Unfortunately, you will need the tool. Hopefully, I am wrong about this.

Some good tips from Tein regarding your situation.

Like Bender_Unit said, check if they're inverted dampers with the adjustment at the bottom. If not you can purchase replacement knobs from BC Racing, I would assume Tein sells them as well. On BC's I believe the hex is for holding the shaft while removing the nut and not linked to the adjustment mechanism.

edit: they're only ~$10 each, looking at some pictures the end looks to be a really tiny hex, much smaller than the one at the end of the shaft that turns the whole thing.

I am hoping if I can skip the ordering and adjust the damper with some simple tools. The knob on google image is just an allen wrench to me

It IS just a very small hex that fits into the top. It is likely very hard finding an allen key that size. If so, maybe you can try finding a roberston screwdriver that fits ? IIRC, it doesn’t take very much torque to adjust.

yes, I tried every possible hex tool and won't fit lol
